MIAMI — Jose Fernandez had a good laugh at the Rockies’ expense Saturday night at Marlins Park.

The 21-year-old rookie not only shut down the Rockies 3-0 with seven scoreless innings, he was also spotted smiling more often than your average patron at a comedy club.

Fernandez (10-5) allowed four hits, no walks and no runs, striking out eight. Fernandez, whose 2.30 ERA ranks third in the majors, beat the Rockies 4-2 on July 23 in Denver.

His confidence was evident Saturday, and it was no surprise to Rockies manager Walt Weiss.

“If I could throw like him,” Weiss said before the game, “I’d be confident too.”

Fernandez threw three 1-2-3 innings, and when he got in trouble, he got out of jams with his breaking ball. The Rockies had runners on first and second with no outs in the second before Fernandez got three consecutive outs on curves. He struck out Wilin Rosario, got Nolan Arenado on a flyball and struck out DJ LeMahieu.

Fernandez also gave up a one-out double to Michael Cuddyer in the fourth before getting two straight outs on curves — Todd Helton on a groundout and Rosario striking out.

“He’s a horse,” Rosario said of Fernandez, whose fastball reached 98 mph. “He throws hard. He has a good breaking ball. He locates well. And he works fast.

“With a good pitcher like him, you have to look for one pitch. Tonight, I was looking more for his fastball.”

In the first inning, after he caught Troy Tulowitzki’s hard line drive, Fernandez giggled and seemed to share a light-hearted “look what I found” moment with the Rockies’ all-star shortstop.

In the top of the fifth, when he struck out Rockies pitcher Jeff Manship on a nasty curveball, Fernandez tried hard to suppress a grin.

“Not everybody is going to like that,” Rosario said of Fernandez’s demeanor. “But I think players should enjoy themselves.”

Weiss said he did not think Fernandez “meant any disrespect to us or to the game — that’s just who he is. He brings a lot of energy and a lot of confidence.”

About the only good news for the Rockies came from first baseman Todd Helton, who singled twice and is now four hits away from 2,500 for his career.

Cuddyer had the other two hits.

Considering that Fernandez was on the mound, the game got away from Colorado in the fourth inning, when the Marlins put up three runs.

De La Rosa is on pace for not only the best season of his career, but one of the best seasons by a pitcher in Rockies history. Three more victories would give him 16, tying his career high set in 2009. His ERA this season is much better than the 4.38 ERA he put up in 2009. After Sunday, he likely will have five or six more starts, so a personal best is well within reach. In his last five starts against the Marlins, he’s 3-1 (1.76 ERA). When Miami came to Coors Field and roughed up the Rockies in late July, the one Colorado victory was supplied by De La Rosa, who pitched six scoreless innings.
